In the given circle, chords AB and CD intersect each other at P. CP = (x − 4) cm, DP = (y + 10) cm, AP = (x − 1) cm, and BP = (y + 1) cm.
If x + 2y = 23, then what is the sum of the lengths of chords AB and CD?
30 cm
32 cm
34 cm
36 cm
Chords AB and CD of a circle intersect each other at point P such that AP=CP.
Show that : AB=CD.
